Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595994, here are decompositions:

5 + 31595989 = 31595994
11 + 31595983 = 31595994
113 + 31595881 = 31595994
127 + 31595867 = 31595994
163 + 31595831 = 31595994
211 + 31595783 = 31595994
223 + 31595771 = 31595994
263 + 31595731 = 31595994

Showing the first eight; more decompositions exist.
